Arctic Mode -ViewCaptureToFile

Hi Guys,

Every time I run -view capture to file (10000 px for example) in arctic mode, my GPU goes nuts and takes a min or so to do it, rendered mode - and the other modes barring raytraced - are super fast and sound CPU based.

Is there are a setting I can change to make the Arctic Mode -viewcapturetofile a CPU operation instead?

Would really appreciate any suggestions.
